[ I reckon there's about $400s worth of carbon-fibre in a frame. There's other costs like R&D, but with minimal changes with some models over the years, it can't amount to much.
The carbon bits aren't the biggest problem. Integration comes at a high price - all the little rubber and plastic bits to fill in gaps and make the bike look smooth have high mould costs. Unit cost of a plastic part is low but that doesn't carry through all that well when you're only talking a couple of thousand units over the product lifetime to amortise the mould cost.
A P3C had some cable stops and a seatpost as proprietary parts.
A P5D has that, plus fork, the entire cockpit, bento box, cover in front of bento, aero bottle, internal Di2 bracket
Now the expectation has become that bikes are designed as systems - which means a heap of those proprietary bits and a lot higher cost for pretty limited benefit.
